00:00:03,033 --> 00:00:08,200

Today I'm gonna introduce a tool used in the maintenance of electronic products

2

00:00:08,466 --> 00:00:09,500

Pliers

3

00:00:10,200 --> 00:00:15,866

pliers used in the repair of electronic products, its mouth is very sharp

4

00:00:16,100 --> 00:00:17,600

similar to a blade

5

00:00:19,966 --> 00:00:25,666

A good or a new pair of pliers can easily cut a piece of paper to shreds

6

00:00:26,300 --> 00:00:29,866

If there is a problem with the cutting mouth of the pliers

7

00:00:30,066 --> 00:00:31,966

It probably won't work well

8

00:00:32,033 --> 00:00:34,800

The pliers like that are basically useless

9

00:00:35,800 --> 00:00:39,566

We do not cut some hard objects when repairing pliers

10

00:00:40,166 --> 00:00:41,000

For example

11

00:00:41,666 --> 00:00:47,200

The tip of the tweezers is bent, I want to cut off the front part and continue to use it

12

00:00:48,366 --> 00:00:50,300

That's definitely not going to work

13

00:00:51,000 --> 00:00:54,600

The cutting edge is easily broken by this hard steel

14

00:00:54,900 --> 00:00:57,966

It is mainly used to cut the desoldering wick

15

00:00:58,233 --> 00:01:03,866

When using desoldering wick, there will be a lot of tin on the front after repeated use

16

00:01:04,900 --> 00:01:07,433

It won't be clean when desolder again

17

00:01:07,600 --> 00:01:09,866

You can cut off the used part

18

00:01:10,733 --> 00:01:15,633

and continue to use the part that has not been pasted with tin in the back

19

00:01:16,033 --> 00:01:24,033

There are also other home appliances like some desktop motherboards or desktop graphics cards that have connectors on them

20

00:01:28,800 --> 00:01:30,733

like this electrolytic capacitor

21

00:01:31,066 --> 00:01:34,566

There are also some connectors such as color ring resistors

22

00:01:34,900 --> 00:01:39,166

These newly bought resistors will have particularly long pins

23

00:01:39,833 --> 00:01:44,166

It is not very convenient to use if it is peeled off directly from the sticker

24

00:01:45,233 --> 00:01:49,566

So we can use the pliers to trim the pins to a more suitable length

25

00:01:57,300 --> 00:02:00,633

Then insert it into the corresponding hole on the motherboard

26

00:02:01,700 --> 00:02:04,633

This makes it easier to weld and operate

27

00:02:06,233 --> 00:02:10,300

Some electronic products such as mobile phones or tablets

28

00:02:11,000 --> 00:02:14,000

These motherboards have some metal shields on them

29

00:02:16,233 --> 00:02:19,133

Some shields are soldered with high temperature solder

30

00:02:19,333 --> 00:02:31,433

In the process of disassembling the shield, it is very likely to damage some other components inside the shield or at the edge of the shield, or even cause a short circuit

31

00:02:31,966 --> 00:02:34,633

At this time, we can also use pliers

32

00:02:34,833 --> 00:02:36,333

to break this shield

33

00:02:39,866 --> 00:02:42,800

This operation must be done under the microscope

34

00:02:43,333 --> 00:02:46,400

Because there are many small components around

35

00:02:46,400 --> 00:02:50,433

And if you are not careful, the pliers may damage the PCB

36

00:02:50,900 --> 00:02:53,233

So the microscope is very necessary

37

00:02:53,633 --> 00:02:56,600

This area is what I cut in advance

38

00:02:57,100 --> 00:03:00,000

If we want to replace the chip in this area

39

00:03:00,566 --> 00:03:02,766

We can cut an area like this

40

00:03:03,366 --> 00:03:06,566

That's all about pliers,thank you for watching
